See post #30 above.......I do have the 4LW. I can honestly say that I don't recall ever using that tool, but it seems that it would be very handy under the right circumstances. I actually don't use any of my Vise Grips very often as it is. I kind of see them mostly as demolition tools of sorts. I'm sure they have many uses, but I find myself using them most often to remove bolts, screws, fasteners, that are stripped, broken off, rusted, etc. I usually try to use the best/correct tool first, but when that doesn't work, I break out the appropriate size/model Vise Grip and let those teeth clamp down on the "stubborn offender." That usually does the trick. Of course the fastener is usually trashed after that. There have been times when I had to remove a fastener that I needed to save. In those cases, I've wrapped the fastener with SEVERAL layers of masking tape to avoid the Vise Grip teeth marks. Sorry for going of course there..... Getting back to the original question. I'd say yes to the larger versions of the 4LW. If I came across good Made in the USA models at reasonable prices, I'd most probably buy them simply for the "just in case I need them" factor.
